EJJ. GOCHRAN. GHUTE. APPLICATION IIL ED MAR- 9I 1908.

UNITED STATES EDWINJ. OOOHRAN, OF STERLING, ILLINOIS.

' CHUTE.

Application filed March 9,

T 0 all whom, it may concern:

Be it known that I, EDWIN J. COOI-IRAN, a citizen of the United States, residing at Sterling, in the county of IVhiteside and State of Illinois, have invented certain new and useful Improvements in Chutes; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention has reference to chutes, of that class which are designed to be secured in the wall of a building, to facilitate the delivery of coal or other products to the basement thereof.

Among the novel features of my device are means for holding the door of the chute in elevated position; means for fastening the door when closed; and an adjustable extension for the mouth of the chute.

My invention is specially adapted to be set in place during the construction of a cement wall or foundation, but can be readily set in plage in a suitable opening in any kind of wal In the drawings: Figure 1 is a side elevation of my invention as it appears in position in the wall. Fig. 2 is a longitudinal section thereof, with the door raised. Fig. 3 is a detail, showing one of the inner faces of the frame 1. Fig. 4 is a perspective, showing the frame 1 and door attached thereto. Fig. 5 is a plan view of the extension, detached.

Similar numbers refer to similar parts throughout the several figures.

1 is a tri-angular frame (in side elevation) provided with a flange 2, adapted to engage the outer face of the wall 3. At its upper edge the flange 2 is provided with ears 4,

supporting a rod 5, on which is hinged a door 6, by means of ears 7 on said door, provided with slots 8, through which the rod 5 passes. At its upper edge the flange 2 is provided with an outwardly projecting ledge 9, on which is a lug 10, adapted to be engaged by a hook 11, fixed to the outer face of the door. When the door is swung upwardly the slots 8 permit it to drop slightly downwards when such' door has attained a substantially vertical position, such downward movement causing the hook 11 and lug 10 to engage each other, and hold the door in elevated po- Specification of Letters Patent.

] sition, as shown in Fig. 2. The same result can be attained by omitting the slots 8 and pivotally attaching the hook 11 to the face of the door 6, but the cost of manufacture would be thereby increased.

The frame 1 is preferably formed of cast metal, and attached thereto in any suitable metal, the shape of the frame 1 permitting the attachment of the chute thereto at the proper inclination, without the necessity of cutting the end of the chute, in order to fit it to the frame.

To the inner face of the door 6 is secured one end of a chain 13, the other end ofwhich can be attached at any desired point to a hook 14, fixed to the upper face of the chute 12. When the door 6 is open, for the deliv ery of any product through the chute, the chain 13 extends through the upper part of the chute and frame, and will not interfere through. When the door is closed, the chain can be hooked in position to prevent the opening thereof. If desired, the chain can be secured so as to permit aslight opening of the door, for purposes of ventilation.

In the outer end of the frame is supported an extension 15, by means of trunnions 16 on the sides thereof, adapted to be supported in ways 17 in the inner side faces of the frame 1. The extension 15 is preferably formed of two parts 18 and 19, the part 18 overlapping the part 19, and being secured thereto by bolts 20 passing through perforations in the plate 18 and slots 21 in the plate 19. By this means the extension can not only be adjusted laterally, so as to fit chutes of varying widths, but greater convenience is permitted. in placing the extension in position. The bolts 20 are loosened and the trunnions inserted in the ways 17, after which the bolts are again tightened, preventing the release of the trunnions. By reversing the operation the extension can be removed. from the chute.

At their lower ends the ways 17 are provided with angular recesses 22, in which the trunnions lodge when the extension is in proper position for use, as shown in Fig. 2. I11 this position the extension is held from movement by stops 23 on the lower face thereof, engaging the lower edge of the flange 2.

When it is desired to close the door of the chute, the extension 15 is raised until the stops 23 clear the flange 2, and. such extenwith the passage of any material there-' manner, is a chute 12, preferably of sheetsion moved inwardly, the engagement of the trunnions with the ways 17 drawing the inner end of the extension upwardly until the outer end thereof is permitted to clear the flange 2, 5 whereupon the entire extension can be'forced into the end of the chute, out of the way of the door. When the door is opened the extension can readily be drawn out into position again.

In the construction of my device I aim to employ the minimum'amount of castmaterial which will be necessary for the-proper support of the sheet-metal portion of the chute, with a corresponding saving in the cost of production-thereof. The ledge 9 not only furnishes a support for the lug 10, but it also provides a protection for the upper edge of the door 6, to prevent, the entrance of rain or moisture at that point.

What I claim as my invention, and desire to secure by Letters Patent of the United States, is:

1. A device of the class named, comprising a cast-metal frame, tri-angular-shaped in side-elevation, and provided with a retaining flange; a door, hinged to said flange, so as to open upwardly; a hook, on the outer face' of said door, adapted to engage with a locking means on said flange, to hold said door in elevated position a sheet-metal chute, attached to said frame and means for locking said door in closed position, substantially as described.

2. A device of the class named, comprising a cast-metal frame, triangular in elevation, and-provided with a retaining flange; a door, hinged to said flange, so as to open upwardly; a lug, supported on said flange; a hook, secured to the outer face of said door, and adapted to engage said lug, to lock said door in opened position a sheet-metal chute, attached to such frame, a chain, secured at its outer end to the inner face of said door and means for fastening the inner end of said chain, substantially as shown and set forth.

In testimony whereof, I affix my signature, in presence of two witnesses.
